tsr RS mutants have rhabdomere and adherens junctions defects. (A–C) The control P[ry+; GMR(Gal4-Pc)]2/CyO female fly was fixed, sectioned and photographed at different magnifications by TEM. (D–F) The intermediate tsr RS mutant has a lower density of ommatidia than the control. Many rhabdomeres are wider than normal or split. The adherens junctions of tsr RS mutants are frequently also wider than the control (compare arrowheads in C and F). (G–I) Ommatidial structures are difficult to see at low magnification in the strong tsr RS mutant. At higher magnification, the rhabdomeres are highly irregular in structure. Unraveled microvilli are frequently seen in the strong mutant (arrow in I). A, D and G were taken at 1900x magnification and B, E and H at 7200x. C, F and I are two-fold blowups of B, E and H. Size markers are all 2 μM.
